It surrounds the rostral part of the brain and interhemispheric commissure and forms part of the limbic system. (MSH) One of three essential structures comprising the limbic lobe, the other two being the hippocampus and parahippocampal gyrus. (CSP)Will keep the NN "gyri" distinct from the BIRN "cortex" regions. Should we later decide the intended meanings are the same, we can set the corresponding classes to be equivalent. In the end, any such correspondence really would depend on how the various cortical areas defined by Brodmann or some other parcellation scheme as defined for the NN gyri relate to those cortical areas assigned to the BIRN coritical regions (BB)., UMLS includes a CUI for "Cingulate cortex" (C0598179) separate from this other for "Cingulate gyrus"., Note that in BrainMap.org, they mere list LimbicLobe.AnteriorCingulate.GrayMatter under which they included Brodmann areas 10, 24, 25, 32, & 33 and LimbicLobe.CingulateGyrus.GrayMatter under which they include Brodmann areas 23, 24, 31, and 32. This indicates not all gray matter contained within the cingulate cortex lies within the cingulate gyrus - at least it doesn't according to BrainMap.org's parcellation., Now I see where my confusion derives from. It relates to the fact this distinction between surface and volumetric, parenchymal structures is a bit unclear in NeuroNames. There sulci are clearly listed as "superficial" (i.e., defining surfaces), whereas gyri as listed as "volumetric structures". The organization of the parenchyma within the lobes of the cerebral cortex are largely given according to complex structures lumped into the "ancillary terms" - e.g., all of the Brodmann areas. The implication for listing "gyri" as volumetric is that the cortical parenchyma lying underneath the gyral surface are also included in these gyral regions. Therefore, it may in fact be correct to set the BIRN "cingulate cortex" == NN "cingulate gyrus". It should also be possible to declare which of the various Brodmann areas are associated with the BIRN defined cortical regions such as "caudal anterior cingulate cortex" (BB)., Was going to assume cingulate cortex for BIRN is equivalent to what is listed as cingulate gyrus in NeuroNames, but clearly that assumption is invalid. In the strictest since, "gyrus" is a description of the surface protuberance between invaginated sulci, while "cortex" typically refers to brain parenchyma with defined cytoarchitectural layers. This is the gross anatomical description of brain tissue. Given this representation is intended to follow the anatomical bases for describing brain structure, it is best we keep cortex and gyri distinct (BB).birnlex_798Cingulate gyrus2015-02-02T00:00:00Regional part of braincingulate regioncingulate areaC0018427TermImport:102106Anterior cingulate gyrusCingulate cortexIsthmus of cingulate gyrusPosterior cingulate gyrusResource:Roadmap Epigenomics ProjectKeywordsAboutRegional part of brainUmlscuiSynonymSuperCategoryHumanSpeciesNeuronamesLinkModifiedDateLabelLimbic lobeIs part ofIdEditorialNoteDefinitionCurationStatusCreatedAbbrev
